To increase the current 19-cent per gallon gas tax to 41.7 cents, and the 15-cent diesel tax to 46.4 cents, and index these taxes to inflation. This would be partially offset by exempting fuel sales from the state sales tax (House Bill 4539). However, neither bill will go into law unless voters approve House Joint Resolution UU in a May 5, 2015 vote, which would increase the state sales tax from 6 percent to 7 percent. When combined with other tax hike bills in the package it represents a net tax increase of around $2 billion.
